Poseidon Water’s proposal for the plant is working its way through various agencies getting approvals necessary to start construction.

Those behind the project argue they have done their own research based on the standards used by the state looking at sea level rise and tsunami hazards in the area of the project and it would not be vulnerable given what was is forecast during its operating life.

The proposed desalination plant in Huntington Beach last year gained needed approvals from the Regional Water Quality Control Board, prompting two environmental groups – Orange County Coastkeeper and the California Coastkeeper Alliance – to sue in September, saying the board’s environmental review of the project was inadequate.
